+Subject: [PATCH] bpo-30622: Change NPN detection: (#2079)
+
+* Change NPN detection:
+
+Version breakdown, support disabled (pre-patch/post-patch):
+- pre-1.0.1: OPENSSL_NPN_NEGOTIATED will not be defined -> False/False
+- 1.0.1 and 1.0.2: OPENSSL_NPN_NEGOTIATED will not be defined ->
+False/False
+- 1.1.0+: OPENSSL_NPN_NEGOTIATED will be defined and
+OPENSSL_NO_NEXTPROTONEG will be defined -> True/False
+
+Version breakdown support enabled (pre-patch/post-patch):
+- pre-1.0.1: OPENSSL_NPN_NEGOTIATED will not be defined -> False/False
+- 1.0.1 and 1.0.2: OPENSSL_NPN_NEGOTIATED will be defined and
+OPENSSL_NO_NEXTPROTONEG will not be defined -> True/True
+- 1.1.0+: OPENSSL_NPN_NEGOTIATED will be defined and
+OPENSSL_NO_NEXTPROTONEG will not be defined -> True/True
+
+* Refine NPN guard:
+
+- If NPN is disabled, but ALPN is available we need our callback
+- Make clinic's ssl behave the same way
+
+This created a working ssl module for me, with NPN disabled and ALPN
+enabled for OpenSSL 1.1.0f.
+
+Concerns to address:
+The initial commit for NPN support into OpenSSL [1], had the
+OPENSSL_NPN_* variables defined inside the OPENSSL_NO_NEXTPROTONEG
+guard. The question is if that ever made it into a release.
+This would need an ugly hack, something like:
+
+	#if defined(OPENSSL_NO_NEXTPROTONEG) && \
+		!defined(OPENSSL_NPN_NEGOTIATED)
+	#	define OPENSSL_NPN_UNSUPPORTED 0
+	#	define OPENSSL_NPN_NEGOTIATED 1
+	#	define OPENSSL_NPN_NO_OVERLAP 2
+	#endif
